  • Mirror-Polished Finish: Expertly hand-polished to a showroom shine that reflects harmful UV rays and eases cleaning.
  • Dual Locking Stability: Features two integrated hex set screws to ensure a rock-solid, rattle-free connection for rails and bimini tops.
  • Heavy-Duty Construction: Precision-machined wall thickness and a reinforced round base provide superior shear strength.
  • Versatile Fit: Available in 22mm (7/8") and 25mm (1") internal diameter options to accommodate standard marine tubing.

Ideal for yachts, pontoons, and center consoles, this hardware provides the uncompromising strength required for high-traffic railing systems.

Frequently Asked Questions

Will this handrail base rust in saltwater environments?
No. Unlike standard 304 steel, this fitting is crafted from AISI 316 stainless steel, which contains molybdenum. This specific alloy provides superior resistance to chloride-induced pitting and crevice corrosion common in saltwater applications.
How do I ensure the railing tube doesn't rattle inside the fitting?
The fitting features a dual-locking mechanism. It is precision-machined to tight tolerances (22.7mm or 25.8mm ID) and includes two integrated hex set screws that clamp the tube firmly in place, eliminating movement and noise.
What size tubing does this fitting accommodate?
We offer two precision sizes: the 22mm model fits standard 7/8 inch OD marine tubing, and the 25mm model fits standard 1 inch OD marine tubing. Please refer to the dimension 'A' in our technical diagram for exact clearance.

Our Roots

Hong Kong Based, 8 Years of Expertise

The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories.

Supply Chain

Invested Factories in Mainland China

To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.
